Endothelin-3 – produced in the lungs, gut, and brain. To produce physical effects, endothelins bind to two types of receptors : Endothelin receptor A (ETA or EDNRA) Endothelin receptor B (ETB or EDNRB) ET-1 reduces blood flow and constricts blood vessels in the kidneys through the activation of ETA receptors. Endothelin-1 (ET-1) has been linked to a number of conditions including pulmonary arterial hypertension (PAH). ET-1 acts via 2 receptors, ETA and ETB. The ET-1 receptor blockers bosentan and sitaxsentan have been shown to be beneficial in patients with PAH. Bosentan blocks both ETA and ETB receptors.

Endothelin (ET) receptors involved in ET-1-induced responses of the longitudinal muscle of the isolated guinea pig ileum were studied. ET-1 caused concentration-dependent contractions, while ET-3 and selective ETB-receptor agonists, IRL1620 and sarafotoxin 6c (S6c), showed little or no effect.

EP - 349. JO - Neuroendocrinology Letters. JF - Neuroendocrinology Letters. SN Endothelin functions through activation of two G protein-coupled receptors, endothelin A and endothelin B receptor (ETA and ETB, respectively). These two subtypes of endothelin receptor are distinguished in the laboratory by the order of their affinity for the three endothelin peptides: the ETA receptor is selective for ET-1, whereas the ETB receptor has the same affinity for all three ET Macitentan (ACT 064992) is an orally active, non-peptide, dual ETA/ETB (endothelin) receptor antagonist with IC50 of 0.5 nM/391 nM. Ambrisentan (LU-208075, BSF-208075) is a highly selective antagonist of the endothelin-1 type A receptor, used in the treatment of pulmonary arterial hypertension (PAH).

BACKGROUND. Endothelin (ET)-1 has potent vascular effects. Two endothelin receptors have been cloned, namely, the ETA receptor, which preferentially binds ET-1, and the ETB receptor, which equally binds ET-1 and ET-3 and preferentially sarafotoxin S6c.

Endothelin-1 (EC50: 17.8 nM), endothelin-3 (EC50: 82.3 nM) and the endothelin ETB receptor-selective agonists, [Ala1,3,11,15]endothelin-1 (EC50: 63 nM) and sarafotoxin S6c (EC50: 0.75 nM) all produced concentration-dependent contractions of human saphenous vein ARTICLE Distribution of Endothelin Receptor Subtypes ET A and ET B in the Rat Kidney Martina Wendel, Lilla Knels, Wolfgang Kummer, and Thea Koch Department of Anesthesiology and Intensive Care Medicine, University Hospital, Dresden, Germany (MW,LK,TK), and Background and Purpose-Elevated levels of endothelin 1 (ET 1) have been reported in cerebral ischemia A role for ET may prove more important if the vascular receptors were changed We addressed whether there is any change in ET receptor expression in cerebral ischemia Methods-The right middle cerebral artery (MCA) was occluded in male Wistar rats for 2 hours with the intraluminal filament Adner M, Cardell L-O, Sjöberg T, Ottosson A, Edvinsson L. Contractile endothelin-B (ETB) receptors in human small bronchi. European Respiratory Journal. 1996;9(2):351-355. The vascular effects of endothelin-1 (ET-1; ETA/ETB agonist), sarafotoxin 6b (S6b; ETA agonist), and IRL 1620 (ETB agonist) were investigated in the isolated canine liver arterial circuit before and after infusions of indomethacin (cyclo-oxygenase inhibitor) and N omega L-nitro arginine methyl ester (L-NAME; nitric oxide synthesis inhibitor).
